In the combined rotary printing and stamping machines for lengths of paper and fabrics of all kinds, as known per se, and as used for example for making wall papers, the exchanging of the printing and stamping rollers is very awkward and takes considerable time, because this roller is not accessible before the inking mechanism mounted in front of it is completely removed from the machine. screws must first of all be removed, and upon this having been done, the complete inking mechanism can be taken down or be lifted up by means of a suitable tackle and set aside.

The re-assembling of the inking mechanism on the machine is of course just as awkward and slow.

To obviate these known defects at least in part, one has endeavoured to extend the bed of the machine on which the inking mechanism is mounted forward to such an extent, that it is possible, as soon as the fixing bolts are removed to remove or draw the inking mechanism from the stamping plate. But this operation is also awkward and takes up a considerable time because even now it is not possible to get access to the stamping roller from the front as is desirable but only from the side.

These disadvantages are completely eliminated by means of the present invention, and this is brought about by arranging the inking mechanism, the ink roller of which lies against the printing and stamping roller, so that it can be swung out.

After the inking mechanism has been swung clear sideways it becomes straight away possible to get easy access from the front to the printing and stamping roller, for the purpose of exchanging it. The machine is ready for work as soon as the inking mechanism has again been swung into position.

The drawing shows the new and improved device in an embodiment shown by way of example, in Figures 1 and 2. Fig. 1 shows a diagrammatic lateral view of this device whilst Fig. 2 shows a front view.

The engraved roller b which acts simultaneously as a printing and stamping roller with its counter pressure roller 0 is mounted on the machine frame a. The endless strip of paper or fabric (Fig. 1) passes from the roller 01 on between the two rollers. The inking mechanism e, wherein the inking roller flies closely against the stamping roller 11, and comprising the ink distributing steel roller 9 and the ink well roller h is no longer, as was hitherto customary, screwed direct on to the bed of the machine, but is instead mounted on a special transverse strap 1'. This strap is supported on the two sides of the machine frame, and is mounted on its left extremity (Fig. 2) on a column In which in its turn is mounted To effect this, the fixing bolts and freely rotatable in the two bearing members 0, p on the outside of the machine frame. A supportingarm Z is provided which is adapted to be adjusted accurately in height and supported in its adjusted position by means of the adjustable collar m, the said supporting arm being swung outwards, i. e. vertically to the plane of the drawing in Fig. 2, during the operation of the machine. This supporting arm therefore does not in any way interfere, when swung out, with the working of the machine.

When the machine is in its working position the strap 2 carrying the inking mechanism is held fixed by means of a cap screw n mounted on the other side of the machine frame, this screw enters and passes through a slot open at the front of this strap.

If it is at any time desired to exchange the stamping roller 11 then this screw n is unscrewed, then the supporting arm or bracket Z is swung under the strap i as shown in Fig. 2, and it is then possible by means of a single manipulation to swing this strap with the inking mechanism mounted thereon as far'out laterally as may be desired, so that the machine is perfectly accessible from the front. As soon as the stamping roller has been exchanged the inking mechanism is again swung into its proper working position and the strap 1' is again fixed in position by means of the screw and then finally the supporting arm or bracket Z is swung back. and the machine is again ready for working.

It consequently only needs a very few and simple manipulations which do not even call for any strenuous effort to bring or move the inking mechanism completely out of the reach of the stamping roller and later on to bring the whole machine back into working order. The effort needed to swing the inking mechanism outwards may be still further reduced if the column is is seated in a ball bearing.

It is of course quite understood that the details of the new device may be diiferent from those shown.

I claim:-

In a combined rotary printing and embossing press having a laterally swingable inking mechanism, a laterally swingable strap carrying the inking mechanism, a column supporting one end of said strap, bearing members supporting said column, a slot in the other end of said strap, a screw stud on the machine frame engaging said slot for fixing said strap, a vertical adjustable arm for supporting said strap in swung position, said arm being turned away from the strap during working of the machine and an adjustable collar on the column for supporting said arm in adjusted position.
